I agree that the topping off is the sign of a minor problem at best. The charging systems of our GPZ are not the most sophisticated and IMHO that tend to overcharge and boil the acid. Interesting note is you really shouldn't top them off with acid as what is boiling off is the water vapor. If you put distilled water in, the acid pH will remain constant, if you top off with acid the acid pH has to get more acidic so it can't be good for the cells.
YMMV,
John

>> I have used both sealed (physically identical to the factory battery and you put the acid in yourself - permanently sealed) and the Yuasa batteries with the caps on each cell. I always get 5-6 years out of them before they require replacement. I prefer the sealed battery as it does not require topping up twice every season like the non-sealed battery does. In my opinion, this constant need to top up the cells must have a negative effect on the useful life of the battery.

>> I've used Yuasa and they are good. Recently I've had two Dekas, the AGM sealed type and really like them.
